CMT 297.108.14M Non-Metal and Laminate Circular Saw Blade by CMT is a professional-grade 350mm carbide-tipped cutting disc engineered for clean, precise results on non-ferrous materials, melamine, and laminated panels. With 108 triple-chip ground (TCG) teeth and a negative -6 deg. cutting angle, this blade is purpose-built for single mitre saws, double mitre saws, and radial saws where chip-free cuts through plastics, composite materials, aluminum, brass, copper alloys, and decorative laminate surfaces are essential. Whether you are a shop professional working with melamine-faced panels or a fabricator processing drawn aluminum profiles, this blade delivers controlled, smooth cuts that protect delicate surface finishes.

Key Features

• 108 TCG (Triple Chip Ground) teeth - the alternating tooth geometry shears through hard and brittle materials like melamine and laminate without chipping edges or tearing surface veneers, reducing rework and waste.
• Negative -6 deg. cutting angle - this hook angle controls the feed rate and reduces grabbing on non-ferrous metals and plastics, giving the operator safer, more stable cuts with reduced kickback risk.
• 350mm (approx. 13-3/4 in.) blade diameter with a 30mm bore - fits single mitre saws, double mitre saws, and radial saws that accept this standard European bore size, maximizing compatibility across common workshop machinery.
• Carbide-tipped (HW) construction - tungsten carbide tips maintain cutting sharpness significantly longer than standard steel teeth, reducing downtime for blade changes during high-volume production work.
• COMBI3 pin hole configuration - supports multiple pin hole patterns (2/7/42, 2/9.5/46.5, and 2/10/60) so the blade mounts securely on a wide variety of mitre and radial saw arbors without requiring adapters.
• 5,500 RPM maximum speed rating - this speed ceiling matches the operating range of standard single and double mitre saws, ensuring the blade runs safely within its structural design limits.
• 3.6mm kerf with 3.0mm plate thickness - the thin kerf minimizes material waste on each cut, which adds up meaningfully when processing expensive laminated panels or non-ferrous stock.

Why This Product

• Designed specifically for non-ferrous metals and laminated surfaces - where general-purpose saw blades leave torn edges or chipped faces, the TCG tooth form and negative hook angle work together to produce chip-free cuts on melamine, plastic, aluminum, and copper alloys without secondary finishing.
• 108-tooth count means more contact points per revolution - on sensitive materials like decorative laminate and composite panels, a higher tooth count translates directly to smoother cut surfaces and cleaner exit edges, reducing the need for sanding or edge-banding corrections.
• Versatile COMBI3 pin hole pattern - instead of stocking multiple blades for different machines, this single blade fits a broad range of mitre and radial saw arbor configurations, making it a practical choice for shops running mixed equipment.
• Rated to 5,500 RPM on a 350mm platform - this combination of large diameter and controlled RPM rating is well suited for cutting wide workpieces like full-width laminated panels and structural aluminum sections in a single pass.

Frequently Asked Questions

What tooth grind does this blade use, and why does it matter for laminate cutting?

This blade uses a TCG (Triple Chip Ground) tooth form. In TCG geometry, teeth alternate between a flat-top raker tooth and a chamfered trapeze tooth. This pattern is especially effective on brittle materials like melamine, laminate, and plastics because the chamfered tooth scores the surface ahead of the raker, preventing chipping on both the top and bottom faces of the workpiece.

What does the negative -6 deg. cutting angle do on a non-ferrous blade?

A negative hook angle means the tooth face tilts backward relative to the direction of rotation. This geometry reduces the tendency of the blade to grab or self-feed into soft materials like aluminum or plastic, giving the operator better control and a safer cutting action compared to blades with a positive hook angle.

What machines is this 350mm blade compatible with?

This blade is rated for use on single mitre saws, double mitre saws, and radial saws. It has a 30mm bore diameter and a COMBI3 pin hole configuration that supports multiple pin hole patterns, broadening compatibility across common European and professional saw arbor styles.

Is lubrication required when using this blade on non-ferrous metals?

Liquid lubricant is recommended when cutting non-ferrous metals such as aluminum, brass, and copper alloys. Wax stick lubrication is not recommended for use with this blade. Proper liquid lubrication extends tooth life and helps maintain cut quality on metallic workpieces.
